Rolex Daytona Yellow Gold — Black Index Dial | Ref. 116508

Born from motorsport and refined by six decades of sustained demand, the Cosmograph Daytona occupies a category of its own within Rolex's catalogue — and within the broader chronograph landscape. Ref. 116508 presents the 40 mm Daytona in 18-carat yellow gold, its fixed bezel engraved with a tachymetric scale whose graduations allow the calculation of average speed directly from the dial. The black lacquered main dial is divided into three registers — a subsidiary seconds at 9, a 30-minute counter at 3, and a 12-hour totaliser at 6 — creating the tripartite visual rhythm that has defined the Daytona since 1965.

Calibre 4130 is Rolex's in-house column-wheel chronograph movement, replacing a Zenith-based calibre in 2000 and representing a generational advance in robustness and service simplicity. Its vertical clutch engages the chronograph without the hand-jolt associated with lateral-clutch designs, and the movement's 28,800 vph beat rate and Parachrom hairspring deliver certified precision of −2/+2 seconds per day. Power reserve of approximately 72 hours is exceptional for a mechanical chronograph of this complexity.

Screw-down pushers with Triplock waterproofing seal the chronograph mechanism from moisture — an engineering solution that makes the Daytona water resistant to 100 metres, a standard no other major Swiss chronograph of comparable vintage achieves consistently. The 18-carat yellow gold Oyster bracelet, with its flat three-piece links and Oysterlock clasp, ensures the watch reads as a unified object from every angle. At £56,995, Ref. 116508 is precisely what a gold sports chronograph should be.
